Our Earth is in danger now. Many kinds of pollution are making it sick. First, air pollution is serious. Cars and factories give off black smoke, so the sky is not as blue as before. People often feel sick because of the dirty air. Second, water is also badly polluted. Some people put rubbish into rivers and lakes, killing fish and making the water not safe to drink. Besides, too many trees are cut down, so more earth is washed away and floods happen more easily. We also make too much rubbish, which fills up rubbish dumps and hurts the Earth. If we don’t act soon, our home will get worse.
